Revealing the Surface Structure of CdSe Nanocrystals

The production of cadmium selenide has been carried out in two different ways. The preparation of bulk crystalline CdSe is done by the High-Pressure Vertical Bridgman method or High-Pressure Vertical Zone Melting. Cadmium selenide may also be produced in the form of nanoparticles. (see applications for … See more Cadmium selenide is an inorganic compound with the formula CdSe. It is a black to red-black solid that is classified as a II-VI semiconductor of the n-type. Much of the current research on this compound is focused on its See more CdSe-derived nanoparticles with sizes below 10 nm exhibit a property known as quantum confinement. Quantum confinement results when the electrons in a material are … See more CdSe occurs in the nature as the very rare mineral cadmoselite. See more Cadmium is a toxic heavy metal and appropriate precautions should be taken when handling it and its compounds. Selenides are toxic in large amounts. Cadmium selenide is a known carcinogen to humans and medical attention should be sought if … See more Three crystalline forms of CdSe are known which follow the structures of: wurtzite (hexagonal), sphalerite (cubic) and rock-salt (cubic). The sphalerite CdSe structure is unstable and converts to the wurtzite form upon moderate heating. The transition starts at about 130 … See more CdSe material is transparent to infra-red (IR) light and has seen limited use in photoresistors and in windows for instruments utilizing IR light. The material is also highly luminescent. CdSe is a component of the pigment cadmium orange See more • Media related to Cadmium selenide at Wikimedia Commons • National Pollutant Inventory – Cadmium and compounds See more WebThe conclusion that the surface of the spheroidal CdSe NCs is primarily composed of {100} facets is supported by the crystal structure of zinc blende CdSe and the similarity of the … Web10.1007/s10854-010-0233-5.
